»Yeah the 600watt can run a 970 just fine. Minimum recomended is 500 for the system with a 970, with 600 you will have wiggle room.
It would leave almost zero wiggle room for getting customization and overclocking anything. You chew up more wattage than you think when you start adding up RAM, how many drives you're running, fans and cooling systems, card readers, sound cards, etc.
I'd really recommend a 750~850W. Can usually find one in the $100~$120 range and it would just give you more options down the road.
